Answer:

x =12

Step-by-step explanation:

We use the Pythagorean theorem

a^2 + b^2 =c^2 where a and b are the legs and c is the hypotenuse

x^2 + 5^2 = 13^2

x^2 +25 =169

Subtract 25 from each side

x^2 +25-25=169-25

x^2 = 144

Take the square root of each side

sqrt(x^2) = sqrt(144)

x = 12

Secured debts must have
Reptile [31]

Answer:

C. Collateral

Step-by-step explanation:

Secured debts are secured by an asset, such as a house or car. The asset serves as collateral for the debt (hence why it's called a "secured" debt). Lenders place a lien on the asset, giving them the right to seize (e.g., repossess or foreclose) it if you become delinquent.
